LEO (Leo AI)

Leo AI is an AI engineer for mechanical engineering teams built on what the homepage calls a Large Mechanical Model, trained on 3D CAD data rather than text alone. It connects to CAD and PLM, reads native 3D geometry, and helps engineers review designs, find and reuse parts, generate and edit CAD, and answer technical questions with cited sources.

Leo is CAD agnostic per the homepage FAQ: it works with SolidWorks, Creo, Siemens NX, Autodesk Inventor, Fusion 360, Onshape, and CATIA V5, and integrates with PTC Windchill, Siemens Teamcenter, SolidWorks PDM, and Autodesk Vault. It reads the latest version of files without copying the vault, and the team controls exactly what it can access. Answers are grounded in the team's PLM data and vendor parts, including a stated catalog of more than 120M vendor parts.

Its Inspector capability reviews an assembly, folder, or STEP file and returns issues ranked by severity, each tied to the exact part, the location in the geometry, and the rule behind it, covering geometry, interfaces, tolerances, GD&T, and company standards. Leo also generates parts and assemblies from text, images, and drawings, then rebuilds them in the team's CAD as editable, parametric models with a full feature tree, and it identifies formulas and runs engineering calculations with citations to trusted sources.
